asp.net微信开发已关注用户管理步骤详解

公众号可通过本接口来获取帐号的关注者列表，关注者列表由一串OpenID（加密后的微信号，每个用户对每个公众号的OpenID是唯一的）组成。一次拉取调用最多拉取10000个关注者的OpenID，可以通过多次拉取的方式来满足需求。

接口调用请求说明

http请求方式: GET（请使用https协议）

返回结果:

{ "total":23000, "count":10000, "data":{" openid":[ "OPENID1", "OPENID2", ..., "OPENID10000" ] }, "next_openid":"OPENID10000"}

获取用户列表绑定用户信息的后台代码，已包括，修改备注名，将用户移动到分组，新建分组代码

分组统计，用于显示每个分组的已存在人数，无其他作用

上代码：
